Do you mean the foliage spawning?

I'll have a think this afternoon. Using a Whittaker Diagram is the obvious choice but I've never satisfactorily come up with a system to calculate humidity. I guess you'd need...

Not at present but I suppose it's something I could work into the editor. If you check out the original library at this link there is a standalone preview application...

Add a world->noise origin offset, which should enable World Origin Rebasing functionality to work, enabling vastly bigger levels.

I'm not able to look at code for a few days, but it's most likely an issue with the pawn tracking not working correctly. Are you removing the player pawn?

No, you shouldn't remove it, you'll need to retain the pawn with the CGTerrainTracker component otherwise the terrain will be removed.
